2025 Congressional Fellows reflect on their terms
Each year, the American Nuclear Society awards the Glenn T. Seaborg Congressional Science and Engineering Fellowship to two members. Those recipients then spend a year in Washington, D.C., contributing to the federal policymaking process by working in either a U.S. senator’s or representative’s personal office or with a congressional committee.
It has been nearly six months since the 2025 Congressional Fellows provided their midterm updates on their time on the Hill. Now, as their fellowships draw to their close, Jacob Christensen and Mike Woosley are looking back on what they accomplished, what they learned, and much more.

The paper studies the case of shrinking cylindrical gas bubbles acting as a radial piston and generating acceleration waves. The behavior of such waves and their improbable transformation into shocks are illustrated theoretically, as well as through some examples inspired by experimental data. The use of rational extended thermodynamics enables us to highlight the relevance of the dissipation and the possible role played by dynamic pressure and stress tensor in bubble evolution or shock formation. These results constitute an extension and a completion of a previous work dedicated to the analysis of acceleration waves generated in oscillating spherical bubbles.
